[0026] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.
[0027] Reference Figure 1-5 As shown, an injection-molded crossbeam includes a tube beam 1 and an injection support assembly 2. The two ends of the tube beam 1 are open, and the injection support assembly 2 is integrally injection-molded and fixed on the tube beam 1. The tube beam 1 is manufactured using a water-assisted process, that is, after the melt is injected, water (pressure 10-30MPa) is injected into the mold cavity under high pressure. The water pressure is used to push the melt to uniformly adhere to the inner wall of the circular tube, and rapid cooling is achieved simultaneously.
[0028] Furthermore, the injection-molded bracket assembly 2 is provided with multiple connection holes 3, which are used for connecting bolts.
[0029] Furthermore, each connection hole 3 is equipped with an adjustable washer 4. The adjustable washer 4 is used to adjust the installation distance of the injection molded bracket assembly 2. Specifically, the adjustable washer 4 includes a movable washer 41 and a fixed washer 42. The opposing surfaces of the movable washer 41 and the fixed washer 42 are both wedge-shaped. For example, when installing the injection molded bracket assembly 2, there is an error between the injection molded bracket assembly 2 and the automotive parts. By rotating the fixed washer 42 to different positions, the combined thickness of the movable washer 41 and the fixed washer 42 can be adjusted to compensate for the error between the injection molded bracket assembly 2 and the automotive parts.
[0030] For details, please refer to Figure 4 and Figure 5 As shown, the fixed washer 42 has a through-hole in the middle, and a connecting ring 421 is fixed in the middle of the fixed washer 42. Limiting grooves 4211 are evenly opened on the outer surface of the connecting ring 421. The movable washer 41 has a through-hole in the middle, and a limiting tooth block 411 that mates with the limiting groove 4211 is fixed in the through-hole of the movable washer 41. By removing the movable washer 41, the position of the movable washer 41 can be adjusted. After adjustment, the movable washer 41 is put on the connecting ring 421, and the limiting tooth block 411 is inserted into the limiting groove 4211, so that the movable washer 41 and the fixed washer 42 are connected and fixed, and the adjustment is completed.
[0031] For details, please refer to Figure 2 As shown, the middle part of the tube beam 1 is cylindrical, and the two ends of the tube beam 1 are elliptical; for example, the two ends of the tube beam 1 gradually transition to an elliptical cross section to form a bending-strengthening zone; the molding process adopts water-assisted injection molding process.
[0032] Furthermore, the injection-molded bracket assembly 2 includes a connecting frame 21, which is integrally injection molded from the same material as the tube beam 1. The outer surface of the connecting frame 21 is provided with through holes, which reduces the weight of the connecting frame 21 and saves materials.
[0033] Specifically, a front connecting column 22 is integrally fixed to the outer surface of the connecting frame 21 for connecting the front of the instrument panel; a steering connecting column 23 is integrally fixed to the outer surface of the connecting frame 21 for connecting the steering mechanism; a large screen bracket 24 is integrally fixed to the outer surface of the connecting frame 21 for connecting the central control screen device; an airbag connecting column 25 is integrally fixed to the outer surface of the connecting frame 21 for connecting the instrument airbag; and a side connecting column 26 is integrally fixed to the outer surface of the connecting frame 21. A positioning stake 261 is fixed to the bottom of the side connecting column 26 to facilitate positioning during installation.
[0034] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
